I wouldn't mind 30fps @720p in return for next gen gameplay and physics 1080p @60fps is like a old $#@! with a new dress, I wanna see incredible physics at some point in my life

Frame rate screaming is mainly a FPS hardcore careabout. 30fps for everything else shouldn't be an issue, and they won't be going for more than that over other items.

The visual fidelity is always a priority at the beginning to try to show it off, and will continue to improve over time. The lighting has been one of the more impressive things.

The change in game play usually takes a couple years for them to figure out where it's going to evolve to. First round of games development on a new gen will have a lot of feelers to figure try to develop stuff that's new and exciting, but it's not until year 2-3 that you usually see what takes it to the next step.

Not sure what exactly you're after in terms of physic's engines, I'm sure they're be improvements but most games have pretty good physic engines today. They came a long way from the beginning to ending of last gen.

I'd not trade the minor improvements you'll see in physic's for lower visual fidelity (though I don't think the improvements in physic's are going to use up the resources such that it would reduce the visual fidelity in the first place.)

I'm sure the PS4 is capable of 1080p at 30 frames per second. At least, I hope 1080p is the norm. Clearer visuals help illustrate next-gen gaming.
